Technical Field

[0001] This application relates to the technical field of cryogenic control, and in particular to an integrated cryogenic control device. Background Technology

[0002] Currently, cryogenic control devices are widely used in industries, scientific research, and grain storage. They typically employ uniformly distributed cold water branch pipes to supply cold water to the target area and lower the temperature of the target area to provide a stable low-temperature environment.

[0003] Existing cryogenic control devices typically employ a decentralized design to provide a stable supply of chilled water to the chilled water branch pipes. This design separates core components such as heat exchangers, compressor refrigeration systems, and water storage tanks, and then connects them to external pipes to supply water to the chilled water branch pipes. While this method offers high heat exchange efficiency, it suffers from low equipment integration, a large footprint, and requires complex piping. Consequently, the cryogenic control device cannot be flexibly arranged according to chilled water supply needs, making it difficult to adapt to diverse cooling demands. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide an integrated cryogenic control device with high integration, flexible layout and low maintenance cost.

[0005] An integrated cryogenic control device includes a housing, the interior of which is provided with a first installation area, a second installation area and a third installation area. A water storage tank, a water distributor and a water collector are installed in the first installation area. The water storage tank, the water distributor and the water collector are connected by pipelines to form a supply and return water system for circulating cold water.

[0006] The second installation area is equipped with a plate heat exchanger and a compressor, and the third installation area is equipped with a finned radiator. A refrigerant circulation pipeline is connected between the plate heat exchanger, the compressor, and the finned radiator. The refrigerant circulation pipeline is sequentially connected to the plate heat exchanger, the compressor, and the finned radiator to form a refrigeration system for cooling water. A heat exchange circulation pipeline is connected between the water storage tank and the plate heat exchanger to allow water in the water storage tank to flow into the refrigeration system for cooling.

[0007] By adopting the above technical solution, the first installation area, the second installation area and the third installation area cooperate with each other to integrate components such as water storage tank, water distributor, water collector, plate heat exchanger, compressor and finned heat sink into the inside of the box, and form a water supply and return system for circulating water supply to cold water branch pipes and a refrigeration system for cooling water, which greatly reduces the footprint of the equipment, adapts to the cold water supply needs of different scenarios, and facilitates the circulation supply of cold water in different scenarios.

[0008] This application further specifies that: the housing includes a bottom plate, a mounting plate, and a top plate arranged in ascending order; the edge of the housing is provided with multiple vertical beams fixedly connected to the first mounting plate, the second mounting plate, and the top plate; the first mounting area and the second mounting area are located between the bottom plate and the mounting plate; the third mounting area is located between the mounting plate and the top plate; and the mounting plate is provided with through holes for refrigerant circulation pipelines to pass through.

[0009] By adopting the above technical solution, the base plate, mounting plate, top plate and vertical beam work together to design the first installation area, the second installation area and the third installation area in a layered manner, which improves the space utilization rate.

[0011] By adopting the above technical solution, the three-way regulating valve and the circulation branch pipe work together to achieve the mixing and circulation of return water in the return water pipe and cold water in the supply water pipe, thereby reducing the cooling capacity consumption of the water storage tank.

[0012] This application is further configured such that: a gas-liquid separator, a filter, and an expansion valve are installed in the second installation area; the gas-liquid separator is connected between the plate heat exchanger and the compressor; the filter and the expansion valve are sequentially connected between the finned radiator and the plate heat exchanger; and the gas-liquid separator, the filter, and the expansion valve are all connected to the refrigerant circulation pipeline.

[0013] By adopting the above technical solution, the gas-liquid separator and filter are connected to the refrigeration system through the refrigerant circulation pipeline, which can filter and remove liquid refrigerant or impurities in the refrigerant during the refrigeration cycle, thereby extending the service life of the compressor.

[0014] This application further specifies that: a second circulation pump is installed at the outlet end of the heat exchange circulation pipeline near the water storage tank, and a flow switch is installed at the inlet end of the heat exchange circulation pipeline near the water storage tank.

[0015] By adopting the above technical solution, the flow switch can monitor the water flow at the inlet of the water storage tank. When the second circulation pump stops running, the flow switch can effectively prevent the water in the water storage tank from flowing back in the heat exchange circulation pipeline.

[0016] This application is further configured such that: a fan is installed in the third installation area and in front of the finned heat sink; an upper housing is provided in the rear of the third installation area; a protective plate is provided in the front of the third installation area; and grilles for air circulation are provided in both the upper housing and the protective plate.

[0017] By adopting the above technical solution, the upper casing and the protective plate can protect the outside of the fan and the finned heat sink to improve the safety of the equipment during operation.

[0019] By adopting the above technical solution, the pipe rack can organize and limit the cold water branch pipes entering the box body, thus avoiding the cold water branch pipes from becoming messy.

[0020] This application is further configured such that: an electrical control box is installed on the base plate, the electrical control box is equipped with electrical control components, the vertical beam is a multi-segment bent structure, and the vertical beam is bent to form a groove for cable laying.

[0021] By adopting the above technical solution, the electrical control box integrates and installs electrical control components, which facilitates the control of different components and improves the automation control effect of the low temperature control device. At the same time, the groove on the vertical beam facilitates the wiring of the connecting cables of different components and effectively prevents the cables from becoming messy.

[0022] This application further specifies that: the bottom of the box is fixedly connected to symmetrically distributed support frames, and the bottom of the support frames is provided with shock-absorbing pads.

[0023] By adopting the above technical solution, the shock-absorbing pads at the bottom of the support frame can buffer and reduce vibration during equipment operation, thereby improving the stability of the equipment during operation and reducing environmental noise.

[0024] In summary, the beneficial technical effects of this application are as follows:

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] Reference Figures 1-9 The present application discloses an integrated cryogenic control device, which includes a housing 1. The housing 1 has a first installation area 101, a second installation area 102 and a third installation area 103. The first installation area 101 is equipped with a water storage tank 2, a water distributor 3 and a water collector 4. Multiple cold water branch pipes are connected between the water distributor 3 and the water collector 4. The water storage tank 2, the water distributor 3 and the water collector 4 are connected by pipelines to form a water supply and return system that circulates water to the cold water branch pipes.

[0039] The second installation area 102 is equipped with a plate heat exchanger 5 and a compressor 6, and the third installation area 103 is equipped with a finned radiator 7. A refrigerant circulation pipeline 8 is connected between the plate heat exchanger 5, the compressor 6, and the finned radiator 7. The refrigerant circulation pipeline 8 is connected to the plate heat exchanger 5, the compressor 6, and the finned radiator 7 in sequence to form a refrigeration system for cooling water. A heat exchange circulation pipeline 9 is provided between the water storage tank 2 and the plate heat exchanger 5 to allow the water in the water storage tank 2 to flow into the refrigeration system for cooling.

[0040] Reference Figures 1-5 The housing 1 includes a bottom plate 11, a mounting plate 12, a top plate 13, and vertical beams 14. The bottom plate 11, mounting plate 12, and top plate 13 are distributed from low to high. The first mounting area 101 and the second mounting area 102 are located between the bottom plate 11 and the mounting plate 12, and the third mounting area 103 is located between the mounting plate 12 and the top plate 13. Multiple vertical beams 14 are evenly distributed along the edge of the housing 1 and are fixedly connected to the first mounting plate 12, the second mounting plate 12, and the top plate 13 by bolts. Thus, the bottom plate 11, the mounting plate 12, the top plate 13, and the vertical beams 14 are assembled into the housing 1 to highly integrate the installation of the water storage tank 2, the water supply and return system, the refrigeration system, the refrigerant circulation pipeline 8, and the heat exchange circulation pipeline 9. This achieves the integration, modularization, and lightweighting of the low-temperature control device, reduces the space occupied by the low-temperature control device, and facilitates its placement in different locations in the bulk grain silo to circulate water to the cold water branch pipes, thereby improving the cooling effect in the bulk grain silo.

[0041] Reference Figure 1 and Figure 2The water storage tank 2 is fixedly connected to the base plate 11 by bolts. The bottom of the mounting plate 12 is fixedly connected to the first bracket 104 by bolts. The water distributor 3 and the water collector 4 are both fixedly connected to the first bracket 104 by bolts, and the water distributor 3 is located below the water collector 4. A water supply pipe 31 is provided between the water storage tank 2 and the water distributor 3. The water supply pipe 31 is connected to the water storage tank 2 so that the cold water stored in the water storage tank 2 flows to the water distributor 3 and is distributed to the interior of the cold water branch pipe through the water distributor 3. The water distributor 3 is provided with several evenly distributed branch pipe interfaces 32. The cold water branch pipes are threaded to the branch pipe interfaces 32. In addition, the distributor 3 is also equipped with valves corresponding to each branch pipe interface 32 to independently open and close the cold water branch pipes, so as to facilitate the precise delivery of cold water to different cold water branch pipes. A return water pipe 41 is provided between the water storage tank 2 and the water collector 4 to allow the water supply to flow back to the water storage tank 2. The return water pipe 41 is connected to the top of the water storage tank 2, and the water collector 4 is connected to the other end of the cold water branch pipe. The heated water in the cold water branch pipe flows back to the water collector 4 and then back to the interior of the water storage tank 2 through the return water pipe 41, thereby realizing the circulation of cold water to facilitate heat dissipation inside the bulk grain silo.

[0042] Reference Figure 1 , Figure 5 and Figure 6 The surface of the base plate 11 is also provided with a second bracket 105, which is fixedly connected to the base plate 11 by bolts. The first installation area 101 is provided with a circulation pump 33 connected to the water supply pipe 31. The circulation pump 33 is fixedly connected to the top of the second bracket 105 by bolts. When the circulation pump 33 is running, it can drive the cold water stored in the water storage tank 2 to flow to the water supply pipe 31. After being divided by the water distributor 3, it flows into different cold water branch pipes. The water collector 4 collects the heated water at the other end of the cold water branch pipe and returns it to the interior of the water storage tank 2 through the return water pipe 41, thus forming a cycle of supplying cold water and returning hot water.

[0043] Reference Figure 6 and Figure 7 A three-way regulating valve 42 is installed on the return water pipe 41 and near the water storage tank 2. A circulation branch pipe 43 connected to the three-way regulating valve 42 is connected to the water supply pipe 31. During the cold water supply and return water circulation process, the water flow rate from the return water pipe 41 to the water storage tank 2 and the water supply pipe 31 can be regulated. When the three-way regulating valve 42 is closed, the water in the return water pipe 41 does not flow through the circulation branch pipe 43 and flows completely into the water storage tank 2. The water storage tank 2 then directly supplies cold water to the water supply pipe 31. When the three-way regulating valve 42 is partially opened, some of the water in the return water pipe 41 can flow through the circulation branch pipe 43 into the water supply pipe 31 and mix with the cold water flowing from the water storage tank 2 into the water supply pipe 31. This allows the cold water to flow to the water distributor 3, thereby recycling the returned water when the return water temperature is low, thus reducing the consumption of cold water in the water storage tank 2.

[0044] Reference Figure 6 and Figure 7 In the first installation area 101, a pressure stabilizing tank 34 is installed, which is connected to the water supply pipe 31 to regulate water pressure balance. The pressure stabilizing tank 34 is fixedly connected to the second bracket 105 by bolts. During the water supply process from the water supply pipe 31 to the cold water branch pipe, the pressure stabilizing tank 34 can balance the water supply pressure, so that the water flow pressure in the water supply pipe 31 and the cold water branch pipe is maintained within a stable range. At the same time, during the start-up and shutdown of the circulating pump 33, by storing and releasing water, sudden changes in water pressure in the water supply pipe 31 can be avoided, reducing pipeline wear.

[0045] Reference Figure 6 and Figure 7 A bypass pipe 35 connects the water supply pipe 31 and the return water pipe 41. A bypass valve 351 for adjusting the supply and return water pressure is fixedly installed on the bypass pipe 35. When the water pressure in the water supply pipe 31 is high, the bypass valve 351 opens, allowing some water in the water supply pipe 31 to flow into the return water pipe 41 to adjust the supply and return water pressure.

[0046] Reference Figure 2 and Figure 8 A third bracket 106 is provided on the top of the base plate 11 and between the first installation area 101 and the second installation area 102. The third bracket 106 is fixedly connected to the base plate 11 by bolts. The plate heat exchanger 5 is installed on the third bracket 106 by bolts. The heat exchange circulation pipeline 9 includes an outlet pipe 91 and an inlet pipe 92. The outlet pipe 91 is connected to the inlet end of the plate heat exchanger 5 so that the hot water in the water storage tank can flow to the plate heat exchanger 5. The inlet pipe 92 is connected to the outlet end of the plate heat exchanger 5 so that the cooled water can flow into the water storage tank 2 for storage.

[0047] To ensure that the water in the storage tank 2 can flow to the plate heat exchanger 5 for cooling, a second circulation pump 93 is installed on the outlet pipe 91. When the second circulation pump 93 is running, it can drive the hot water in the storage tank 2 into the plate heat exchanger 5 through the outlet pipe 91, and allow cold water to flow into the storage tank 2 through the inlet pipe 92. At the same time, a flow switch 94 is installed on the inlet pipe 92 to monitor the cold water flow in real time, so as to adjust the operating power of the second circulation pump 93 and prevent the water in the storage tank 2 from flowing back in the inlet pipe 92.

[0048] Reference Figure 8In the second installation area 102, a gas-liquid separator 61, an expansion valve 81, and a filter 82 are installed. The gas-liquid separator 61 is connected between the plate heat exchanger 5 and the compressor 6. The compressor 6 and the gas-liquid separator 61 are evenly fixed to the base plate 11 with bolts. The filter 82 and the expansion valve 81 are connected in sequence between the finned radiator 7 and the plate heat exchanger 5. The gas-liquid separator 61, the filter 82, and the expansion valve 81 are all connected to the refrigerant circulation pipeline 8.

[0049] During the operation of compressor 6, the refrigerant is driven to flow along refrigerant circulation pipeline 8. When the refrigerant flows from plate heat exchanger 5 to compressor 6, gas-liquid separator 61 separates the liquid refrigerant to prevent liquid refrigerant from entering the interior of compressor 6 and extend the service life of compressor 6. The high-temperature and high-pressure refrigerant gas after being compressed by compressor 6 flows to finned radiator 7. After being cooled by finned radiator 7, the refrigerant is rapidly cooled down and expands to a low-temperature and low-pressure state through expansion valve 81, so that the refrigerant can exchange heat with water in plate heat exchanger 5. In addition, when the refrigerant flows from finned radiator 7 to expansion valve 81, impurities in the refrigerant can be filtered through filter 82 to reduce equipment damage.

[0050] Reference Figure 1 and Figure 5 In the further implementation process, in order to facilitate the connection between the refrigerant circulation pipeline 8 and the finned radiator 7 in the third installation area 103, a through hole 121 is provided on the mounting plate 12 for the refrigerant circulation pipeline 8 to pass through.

[0051] A fourth bracket 107 is fixed to the top of the mounting plate 12 near the front edge by bolts. A fan 71 is provided in the third mounting area 103 and in front of the finned radiator 7. The fan 71 is fixedly connected to the fourth bracket 107 by bolts. When the fan 71 is running, it can drive the air at the finned radiator 7 to flow quickly, thereby quickly cooling the refrigerant to facilitate refrigeration.

[0052] Reference Figure 3 and Figure 4 The front side of the third installation area 103 is provided with a protective plate 151, and the rear side of the third installation area 103 is provided with an upper housing 15. The protective plate 151 and the upper housing 15 can protect the outside of the finned heat sink 7 and the fan 71 to improve the safety of the equipment during operation. Both the protective plate 151 and the upper housing 15 are provided with grilles for air circulation, which facilitates air circulation while ensuring the protective effect.

[0053] The bottom of the upper housing 15 is provided with a lower housing 16 that is detachably and fixedly connected to the vertical beam 14. A pipe rack 161 is fixed to the lower housing 16 near the bottom by bolts. The pipe rack 161 has multiple through holes for cold water branch pipes to pass through. The multiple through holes are evenly arranged in a rectangular array. This facilitates the connection between the cold water branch pipes and the water distributor 3 and water collector 4 inside the housing 1, while also allowing the cold water branch pipes to be sorted and limited to prevent them from entering the housing 1 in a messy manner. In addition, the front side of the lower housing 16 is provided with a door 162 that is hinged to the vertical beam 14. The door 162 is fixedly connected to the vertical beam 14 by a hinge, allowing the door 162 to be rotated and opened, which facilitates the maintenance of the equipment in the first installation area 101 and the second installation area 102.

[0054] Reference Figure 1 An electrical control box 17 is bolted to the base plate 11. The electrical control box 17 contains electrical control components, which are connected to various parts via cables. The electrical control components include air switches, power conversion modules, controllers, relays, etc., all of which use existing technologies and will not be described in detail here. The electrical control components only need to control the operation of the equipment according to the sensor signals. In addition, the vertical beam 14 has a multi-segment bending structure, which improves the structural strength of the vertical beam 14 and forms grooves 141 on the vertical beam 14. The cables in the box 1 can be evenly laid along the grooves 141, effectively avoiding cable mess.

[0055] The bottom of the housing 1 is fixedly connected to symmetrically distributed support frames 18. The support frames 18 are welded and fixed to the bottom of the base plate 11. The bottom of the support frames 18 is fixedly connected to the shock-absorbing pads 181 by bolts. When the equipment inside the housing 1 is running, the shock-absorbing pads 181 can buffer and reduce vibration at the bottom of the support frames 18 to prevent the housing 1 from vibrating violently, thereby improving the stability of the equipment during operation.

[0056] The implementation principle of this embodiment is as follows: By cooperating with the base plate 11, mounting plate 12, first bracket 104, second bracket 105, third bracket 106, and fourth bracket 107, the water storage tank 2, water distributor 3, water collector 4, plate heat exchanger 5, compressor 6, and finned radiator 7 are integrated and installed inside the housing 1. With the cooperation of the water supply pipe 31, return water pipe 41, refrigerant circulation pipeline 8, and heat exchange circulation pipeline 9, a water supply and return system for circulating water to the cold water branch pipe and a refrigeration system for cooling the water body are formed to achieve continuous circulation supply of cold water.

[0057] In the specific implementation process, the electrical control components in the electrical control box 17 accurately control the start-up, shutdown and operation status of each device according to the sensor signals. First, the circulation pump 2 93 is started to transport the water stored in the water storage tank 2 to the plate heat exchanger 5, and then return to the inside of the water storage tank 2 through the water inlet pipe 92. When the water circulates between the water storage tank 2 and the plate heat exchanger 5, the plate heat exchanger 5 is connected to the compressor 6 through the refrigerant circulation pipeline 8, which makes the compressor 6 run and drives the refrigerant to circulate in the refrigerant circulation pipeline 8. The water and the refrigerant exchange heat through the plate heat exchanger 5, thereby cooling the water and storing the cold water in the water storage tank 2.

[0058] When cold water needs to be supplied to the cold water branch pipe, the circulation pump 33 is turned on, and cold water is delivered to the distributor 3 through the water supply pipe 31. The cold water is also delivered to each cold water branch pipe through the branch pipe interface 32. The other end of the cold water branch pipe is connected to the water collector 4, so that the water collector 4 collects the returned cold water and delivers it to the water storage tank 2 through the return water pipe 41, so as to form a closed loop of cold water supply, which facilitates the continuous water supply to each cold water branch pipe.

[0059] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
